Reading Skip Gundlach's discussion of fixing "Flying Pig" and having
built 4 boats with epoxy, the issue of primary rather than secondary
bonding is often on my mind. A primary, (chemical) bond is much
stronger than a secondary mechanical bond. There ought to be a way to
promote a chemical bond (polymerization) with the underlying
material. I wonder if treating it with something like epoxy paint
remover first would do this. I need to get back in touch with a
polymer chemist friend of mine about this cuz I think it'd be a good
product if it'd work.


Is it ever possible to get a primary bond between polyester resin and epoxy?
I don't know, but I've been told "no" by so many people over the years that
I tend to act as if I believe it.
